arXiv:2606.31216v1 Announce Type: cross Abstract: The Doppler velocity log (DVL) velocity measurements are critical to the accuracy of autonomous underwater vehicle (AUV) navigation solutions and, consequently, to mission success. To ensure accurate measurements, the DVL is commonly calibrated before mission start while the AUV sails on the water surface, receiving global navigation satellite system (GNSS) signals that provide accurate reference measurements. Conventionally, Kalman filter-based approaches are employed during calibration to estimate the scale factor and misalignment errors. How
The continuous drive for higher autonomy in underwater vehicles necessitates improved sensor accuracy and reliability, pushing research in calibration techniques.
Accurate DVL calibration is crucial for the navigation of autonomous underwater vehicles, impacting their effectiveness in military, scientific, and commercial applications.
More precise calibration methods for DVLs will lead to enhanced navigation accuracy for AUVs, potentially expanding their operational envelopes and mission success rates.
